Hey, my mom drives a huge SUV, and she needs to. We have 6 people in my family. All of my bothers and sister play soccer, and my mom is activly involved in soccer. When we go on 2 week trips to the mountains in colorado we have pleny of space for the whole family + 2 weeks of luggage + the dog.... cant do that in a car.
Well I dont know what the permativity of a wall is, but the permitivity of dry soil is 2.656E-11 and conductivity of dry soil is 10^-5 Seimens per meter. That gives a complex permetivity of ec = (2.656E-11 - j(10^-5/120E9)) which is (2.213E-11 - j8.333E-17). ok, so the loss is the real part of (j*120E9*sqrt(1.256E-6*ec)) where ec is the complex permitivity. That gives a loss of.001191 Nepers/meter. In other words, the electric field is reduced by only 0.01035 db/meter. You would have to go almost more than 280 meters before the signal is cut is cut in half. thats not very opaque! Well, in dry soil at least. Increasing conductivity with water or metal has a much greater effect on the signal than dry walls or air do. -Brandon
They havnt made it to space yet, but at least their rockets dont explode. Check out this amatuer rocket effort. They have some great videos from outside of their LV1 rocket.

Hmmm, lets see, we have billions of dollars worth of revenue. I know lets spy on people!
Come on people, this is not the cold war here, they make and sell hardware, they dont take your credit card numbers and buy themselves a new TV! Grow up...
Yes Yes, I know about the serial numbers, here is a radical idea, maybe they really were trying to stop illegal sales of processors? Wow, what an idea!! If not, then who cares if they know you have a PIII, big deal...
-Sorry, this is my first post, I know this wont give me a good rep..:)

To bad that wont work anymore once you get past 10GHz. Luckily there are still a few numbers between now and that time.

17 GHz bandwidth is not "wide enough" ?

We use H2O2 with sulfuric acid to remove organics from wafers. Its strong enough to blister your skin if you touch it though.
